This TV program has been one of my favorites--it introduces into many real world scenes and phenomena, especially where the scientific theories are applied into empirical activities. Yesterday I saw an episode which showed of a place where there is crocodiles and some kind of antelopes (with smaller size). The crocodile normally can sustain themselves by feeding on the fishes in the pond. But the fish may not be enough once in a while (or the crocodile wants to try a new flavor). So the crocodile may lurch below the water surface, waiting the antelopes or deers to drink water. That's when I find it interesting. An antelope had to near the pond even though she knows there was danger, or it could die of thirst. It slowly and carefully came closer to the body of water, which seemed innocuously normal, only a reflection of the blue sky (even to me, a view in front of the TV set, I didn't believe there's a crocodile hiding underneath). Just alongside the small lake, the little creature still couldn't calmly quench its thirst--it quickily dipped once or twice, and jumped away immedia- tely! That act reminded me of human behavior--this kind of uncertainty also exists in animal psychology! From the antelope's behavior--stealthy water-taking means it's aware of a crocodile's spying; jumping away (from the menace) proactively means it calculated that the crocodile would launch attack when it's preoccupied with some "business," I think any creature, as long as it is endowed with perceptionary organs such as a pair of eyes, its ,ental matrix is conditioned or framed by these available "data"--the antelope may have witnessed its fellows victimized that way, so that memory enables it (even burdensomely, unfortunately) to, forces it to behave paranoidly each time it tried drinking water. --
